System description<\/h2><\/div>

TINES\u00ae ERS Encapsulated Rail Fastening System<\/strong> is a direct rail fastening solution designed for the construction of ballastless track systems<\/span>.<\/p>\n

In the <\/span>TINES\u00ae ERS System<\/strong>, the rails are continuously fastened along their entire length within rail channels using <\/span>TINES\u00ae Polyrail 60\/65 <\/strong>polyurethane elastomer<\/span>. The elastomer forms a permanently elastic, homogeneous encapsulation around the rail, performing two essential functions: securely fastening the rail within the rail channel and providing continuous support to the rail foot.<\/span><\/p>\n

Thanks to the excellent adhesion of TINES\u00ae Polyrail<\/strong> materials to both concrete and steel surfaces, no additional mechanical fastening of the rails with bolts or screws is required<\/b>.<\/p>\n

The continuous rail fastening provided by the TINES\u00ae Polyrail<\/strong> system ensures durable and resilient transfer of loads generated by train traffic and thermal expansion of the rails, including forces acting in both the vertical and horizontal directions. As a result, the TINES\u00ae ERS System<\/strong> effectively reduces vibration and noise generated by passing trains.<\/p>\n

The material properties of the elastic TINES\u00ae Polyrail 60\/65<\/strong> encapsulation also contribute to protecting the surrounding railway infrastructure against stray electrical currents<\/span>.<\/p>\n

As an optional component, the TINES\u00ae ERS System<\/strong> may incorporate the continuous TINES\u00ae Railstrip <\/strong>elastic under-rail pad<\/span>, which allows the stiffness of the rail support to be adjusted to meet specific project requirements.<\/p>\n<\/div>

System applications<\/strong><\/div><\/h2><\/div>
<\/div><\/div>

The TINES\u00ae ERS Encapsulated Rail Fastening System<\/strong> is designed for use in ballastless track structures<\/span> on both single-track and multi-track railway lines<\/span>, with s<\/strong>tandard gauge (1,435 mm)<\/span> or broad gauge (1,520 mm)<\/span>. The system is suitable for fastening all Vignole rail profiles<\/span>, including 60E1<\/span>, 49E1<\/span>, and other special rail sections.<\/p>\n

The <\/span>TINES\u00ae ERS System<\/strong> can be used on straight track sections and on horizontal curves with a minimum radius of <\/span>R \u2265 150 m<\/span>, for <\/span>maximum axle loads of up to 260 kN<\/span> and <\/span>operating speeds of up to 250 km\/h<\/span>. It is intended for use on <\/span>mainline railway networks<\/span>, <\/span>metro infrastructure<\/span>, and <\/span>railway sidings<\/span>.<\/span><\/p>\n

The system can be installed on bridges<\/span>, <\/strong>viaducts<\/span>, <\/strong>and tunnels<\/span>, as well as at pedestrian crossings<\/span>, <\/strong>railway-road crossings<\/span>, <\/strong>bicycle crossings<\/span>, <\/strong>turnout areas<\/span>, <\/strong>and intermodal terminals<\/span>. It can also be incorporated into integrated rail-road track systems<\/span> together with the TINES\u00ae LC-L <\/strong>prefabricated track slab<\/span>.<\/p>\n

The TINES\u00ae ERS System<\/strong> is particularly recommended for railway sections where reducing vibration and noise<\/strong> generated by rail traffic is of key importance.<\/p>\n

The TINES\u00ae ERS System<\/strong> complies with the requirements for Category C<\/span> and Category D rail fastening systems<\/span> in accordance with EN 13481-5<\/span>. It is suitable for use on railway networks subject to the Technical Specifications for Interoperability (TSIs)<\/span>, as well as on railway infrastructure not covered by TSI requirements, including metro systems<\/span>, narrow-gauge railways<\/span>, railway sidings<\/span>, private railway infrastructure<\/span>, and functionally isolated railway networks<\/span> intended exclusively for regional or local transport, in accordance with the applicable railway regulations.<\/p>\n<\/div>

System components<\/h2><\/div>
<\/div><\/div>

The TINES\u00ae ERS Encapsulated Rail Fastening System<\/strong> consists of the following components:<\/p>\n

TINES\u00ae Polyrail material system<\/strong><\/span><\/h4>\n

TINES\u00ae Polyrail 60\/65<\/strong> \u2013 a two-component, solvent-free polyurethane elastomer for resilient rail fastening. In the TINES\u00ae ERS System<\/strong>, TINES\u00ae Polyrail 60\/65<\/strong> forms a continuous elastic encapsulation around the rail, bonding it to the side walls and the bottom of the rail channel while providing continuous resilient fastening and support.<\/p>\n

TINES\u00ae Polyrail Primer<\/strong> \u2013 a two-component epoxy primer with dielectric properties. In the TINES\u00ae ERS System<\/strong>, it is used to prime dry concrete substrates (rail channel walls) and steel substrates (rail surfaces or steel rail channels) to improve the adhesion of TINES\u00ae Polyrail 60\/65<\/strong> to these surfaces.<\/p>\n

TINES\u00ae Polyrail 53+<\/strong> \u2013 a two-component epoxy resin with dielectric properties. It is designed for priming both dry and wet concrete substrates (rail channel walls) and steel substrates (rail surfaces and steel rail channel walls) to enhance the adhesion of TINES\u00ae Polyrail 60\/65<\/strong>. It is also used for bonding the continuous TINES\u00ae Railstrip<\/strong> under-rail pad to the bottom of the rail channel, as well as for fixing concrete blocks or TINES\u00ae Railfiller<\/strong> inserts into the rail joint chambers.<\/p>\n

TINES\u00ae Railstrip<\/strong> \u2013 a continuous elastic under-rail pad used optionally in the TINES\u00ae ERS System<\/strong> to reduce the stiffness of the rail support, thereby decreasing noise and vibration transmitted to the surrounding environment. It is bonded to the bottom of the rail channel using TINES\u00ae Polyrail 53+<\/strong> and, together with TINES\u00ae Polyrail 60\/65<\/strong>, forms an additional continuous resilient support layer beneath the rail.<\/p>\n

TINES\u00ae Railshim<\/strong> \u2013 elastic under-rail adjustment shims available in various thicknesses. In the TINES\u00ae ERS System<\/strong>, they are used to adjust the rail position in the vertical plane and to set the rail cant. The shims should be installed at regular intervals of 1.5\u20132.0 m<\/span> along the bottom of the rail channel. When correctly positioned, they do not affect the stiffness of the fastening system.<\/p>\n
